    Another thing that goes along with non condensables is a very high apparent subcooling. And more often than not, a lower than normal evaporating temp.

    It's nitrogen still in the system. Change vacuum pump oil and test the vac pump. Then use a micron gauge. Might sound crazy but one busy year I let mine go too long and it wouldn't pull a good vacuum.
